Abstract (en)
[origin: WO2019121000A1] Actuator (10) comprising a base section (14,14a,14b); a permanent magnet (18,18a,18b); an electro permanent magnet (20, 20a, 20b); a coil (22, 22a, 22b) located around the electro permanent magnet (20, 20a, 20b); a power controller (24, 24a, 24b); and a movable member (28) comprising at least one magnetic target section (36), the movable member (28) being arranged to move to a first position (12) relative to the base section (14,14a,14b), when the electro permanent magnet (20, 20a, 20b) adopts a first polarity, and arranged to move to a second position (46) relative to the base section (14,14a,14b) due to a magnetic field generated by the permanent magnet (18,18a,18b) and the electro permanent magnet (20, 20a, 20b) in combination and acting on the magnetic target section (36), when the electro permanent magnet (20, 20a, 20b) adopts a second polarity. A lock device (50), a handle device (86) and a method are also provided.
